Google has filed a patent currently for a smartwatch that can efficiently draw small sample of blood from human body without the need of pricking needle. Needle is a terror to many people and there are many patients who need to get injected 3-4 times a day. For example, many patients suffering from diabetes have to test their sugar level using finger prick machines in order to ensure that their glucose level is in check. If Google invents such a device, then situation will get better for such patients and blood testing will become less painful.
Google has kept complete silence regarding the details of the device specification. The smartwatch is still in patent phase and the patent application reveals that the smartwatch will first send an ‘abrupt surge’ of gas into a barrel containing a microparticle. This microparticle then punctures the skin to produce a small drop of blood.
“We hold patents on a variety of ideas – some of those ideas later mature into real products or services, some don’t. Prospective product announcements should not necessarily be inferred from our patents”, said Google in an interview to The Verge. It’s not yet confirmed as when the device will roll out, but a smartwatch with such a feature is definitely a welcome. Even though the patent application has not mentioned specifically about diabetes patients but it’s quite obvious that these patients and children are the ones who need special attention. This device, if makes out to the market soon, will contribute hugely in the betterment of mankind.
